I have a new T-ring adapter for Canon EF mounts. This allows you to attach your camera directly to a scope for prime focus photography. They sent me the wrong adapter and I don't want to go thru the trouble of sending it back (it only cost me p350). I'm giving it away to anyone who can use it. You can attach your Canon DSLR to any scope with a 1 1/2in eyepiece socket. The female threads are M42, so if you happen to have any of those great old-school screw-in lenses from older 35mm cameras, you can use them on your DSLR. Let me know if you're interested.
